Updated pacemaker packages that fix several bugs and add one enhancement are nowavailable for Red Hat Enterprise Linux 6.

Pacemaker is a high-availability cluster resource manager with a powerful policyengine.

This update fixes the following bugs:

* Previously, the "port" parameter was declared as required in the fencing agentmetadata. Some devices, however, determine the correct port automatically andtherefore do not need it specified in their configuration. As a consequence,updating configurations that didn't contain the "port" parameter failed with thefollowing error message:

ERROR: apc-fencing: required parameter port not defined

This update modifies the fencing agent metadata so that "port" is not declaredas a required configuration option. As a result, updating configurations inwhich the "port" parameter is not specified succeeds. (BZ#720214)

* Previously, the "start" and "stop" actions were not declared in the fencingagent metadata. As a consequence, the following warning messages were displayedwhen configuring fencing devices:

WARNING: apc-fencing: action start not advertised in meta-data, it may notbe supported by the RA WARNING: apc-fencing: action stop not advertised in meta-data, it may not besupported by the RA

This update adds the "start" and "stop" actions to all fencing agent metadata.As a result, configuring fencing devices no longer displays the aforementionedwarning messages. (BZ#720218)

* Due to an error in the underlying source code, operation failure records werenot removed together with removed resources. Consequently, resources re-definedafter previous deletion were associated with the previous failure records. Thisupdate modifies the underlying source code so that failure records are removedtogether with removed resources. As a consequence, previously deleted resourcesare not associated with any failure records after being re-defined. (BZ#789397)

* Previously, the logic for determining whether a resource is active wasincorrect. Consequently, active resources on nodes in the "UNCLEAN" state wereignored by tools that relied on this logic. This update fixes the logic. As aresult, tools relying on this logic report active resources on nodes in the"UNCLEAN" state as active. (BZ#799070)

* Previously, descriptions of the -v and -V options of the crm_report commandwere swapped in text of its manual pages. Consequently, some users were misleadby unexpected behavior when using these options. This update corrects the textof the manual pages so that they reflect the actual behavior of the crm_reportcommand. (BZ#801351)

In addition, this update adds the following enhancement:

* Pacemaker now uses the libqb library for logging. This provides less verboselogs while still providing the ability to debug and support Pacemaker.(BZ#782255)

All users of Pacemaker are advised to upgrade to these updated packages, whichfix these bugs and add this enhancement.
